Hundreds of errors when loading Java WEBDynpro project .

Question

Hello all,
Almost a year ago, we built some custom webdynpro iviews. Until now everything works fine, but the customer has requested some minor changes .
So I connected to the dev server and loaded the track we had created for this project. The problem is that when we create a project from the DTR, in order to edit it, we get a load of errors, which were ofcourse not occurring when we compiled the project .
For example, this is an error in my Custom Controller "ZHRCOS_P0002_CONTR"
The code was automatically generated by the system when it was created, so if I try to change anything I get the message "This Code is Derived, do you really want to change it?"
inside the code there is the function
infoRecords = GCIContext.createModelNode("Records", true, CMICardinality.MANY, CMICardinality.ZERO_TO_ONE, true, ... etc .
There I get the message
"CMICardinality.MANY cannot be resolved"
I would think that some necessary packages were not loaded during the "Create project" procedure, although I loaded all the dependencies .
But, what I actually see, is that the class <CMICardinality> exists, only that instead of having the constant <MANY>, it has the constant <CARDINALITY_MANY> .
This is something I cannot understand, because the Dynpros were compiled almost one year ago and they are still working fine. Why do I get those problems ?

Answer 1

Thank you both, but I have already tried these approaches. I also tried with other projects and I have the same problem .
Also I noticed that the visual editor seems to have a problem, but I do not know if it is connected to the above .
"Unhandled event loop exception"
I have changed my NWDS to 7.2, but I don't think that the studio version would have any impact on the building of the webdynpro.
